Hi guys, I always wondering, what is reset when reset button is click? Does the setting from address D from HMI will be lost? Does internal memory of PLC is reset? Anything thats not reset? Or just reset sequence? Thanks.

How to connect two NB HMI's to NX102 PLC via Ethernet
NatC posted a topic in NJ Series / Sysmac Studio
I am new to automation systems and devices and I just want to know how to connect two HMI's (each one would control different things) to one PLC using Sysmac Studio and NB-Designer via Ethernet. The model of the PLC is NX1029020 and the HMI's are one NB10W-TW01B and an NB7W-TW01B. I searched for info about this topic online but I couldn't find anything that worked for me, I saw an article from OMRON where they connect two NB's to the CP series, but in my case, NB designer doesn't allow me to insert more than one HMI in the same project, I also found something similar on a youtube video that gave me an idea about how to connect multiple HMIs exporting the pks file and importing it to another HMI project but I still can´t figure out how to add both to my PLC. I would thank you a lot if you could help me with this because I know it's not a rare implementation, just I haven´t found the right way to do it. I also leave the links to the Omron article and the youtube video I found. https://www.myomron.com/index.php?action=kb&article=1554 https://www.youtube.com/watch?v=rXx5lut7G9I -
Hello, I want to know, if it is worthwhile to transfer from Q series to iQ-R? Currently our equipment is using Q series, which ss a vacuum coating equipment with about 10 power instruments, 20 gas controllers, and pumps and so on. As for the analog and X, Y points, Q is quite capable. I can not see any advantage to switch to iQ-R, but some people want to. So I want to know, 1. will Q be outdated in the near future? 2. will use iQ-R cost much more than Q? including peripheral units. 3. has iQ-R really been widely adopted? 4. thoug iQ-R may be powerful, I think use multiple middle size CPU's can be more advantageous, is this right? Many thanks in advance. Ting

I have a huge confusion regarding the retentive timers on FX3GE. According to the programming manual for FX3G(image attached), all retentive timers use the EEPROM. This is very confusing to me because the retentive timers are modifying the measured time constantly in an EEPROM register and EEPROM type of memory is known to be write limited. After a couple of million write cycles the EEPROM registers burnout. I've experienced this myself by constantly using the T250 and after a while it became unusable. The timer stopped counting time after some time. This leads to my decision that retentive timers on FX3GE PLCs are something that should бе used only on rare occasions so as to avoid EEPROM memory burnout. If this is true than the real question comes in: What is an alternative for using retentive timers on FX3GE when you want to measure time between two events. The instruction TTMR for teaching timer is appropriate however this instruction does not exist on FX3G series.

I am trying to online edit a program in a MELSEC QCPU, using GX Works2, but I keep getting this error "A file which does not exist in the PLC was specified" <ES:010a4022> Few weeks ago I had just online edited the same program in the same PLC with the same steps with no problem. There had been no changes to the PLC after that. Just all a sudden when I try to edit yesterday I get this error. Not an expert in Mitsubishi, just started learning the basics. Connection to PLC is by USB cable. Steps I followed to connect to PLC: -Online > Read from PLC -Select PLC Series: QCPU (Q mode) -Select PLC side I/F Serial Setting: Serial USB -Select all target program to Read, then Execute I am editing the file that I had just read from PLC Steps I followed to online edit: -Online > Monitor > Monitor (Write mode) -Execute the function below when mode is changed: Checked all -Edit the program (basically just deleted one -||- contact and drew back the line) -Compile > Online Program Change Then Bam! error get! "A file which does not exist in the PLC was specified" <ES:010a4022> I had tried Verify with PLC, but all results match. Is there something I am missing? Help much appreciated!

I am looking into how to connect/backup the existing programming on some legacy PLC's. I have been trying to find the information on this site, which is awesome! But I feel I am getting lost in all the different software/PLC's types. As I understand it, we have a Melsec-A or A2AScpu. Now there is what appears to be a pin cable when you open the swivel door on the PLC that would allow you to connect it to a PC. Where I am getting lost is "do I need a specific cable for this, I know some pin cables will have the wiring line up differently per the pins" and or "what software would work best to allow me to take a current backup of the existing programming on the PLC." Please understand I am new to PLC's. But I am willing to learn, right now I am thinking about using some older PLC's we have that are not in use to start with so I can learn but I just feel a little overwhelmed with all the differences in both PLC versions and the software you can use. I also think if I can lock in the backup/restore process i will always be in a position to revert back should (more than likely) I make any mistakes. Any help with pointing me a good place to start for the specific PLC I am referring to would be really appreciated.

Limit Number of Character in Data Edit (NA series)
Sin Ching posted a topic in NJ Series / Sysmac Studio
Hi All, I am trying to limit the number of character for user to key in data edit . However, I put numbers inside it shows me invalid number of character. Anyone know how to solve it ? Note; My variable is in String Type -
Hello, everyone I have to query a SICK distance sensor from an L26CPU via the onboard Ethernet interface. I have created a simple protocol which I start with the function block SP_ECPRTCL. Unfortunately it takes at least 25ms until the next telegram is started. The sensor responds within approx. 1.5ms. Does anyone know whether that works faster or is that a limitation when using the predefined protocols? Sensor manual: OD5000, 8021391 (sick.com) (Chapter 7.4) I am grateful for all the hints. Thanks and regards Dave SICK_Protocol.tpc Messaufbau_vTest.gxw

Hi, I have the following configuration where 4 PLC panels, with each having a Q12PH CPU and QJ71E71-100 module. All these QJ71E71-100 are connected to a HUB using straight cable. From the HUB one connection is going to an I-Fix SCADA which is already communicating with all 4 PLCs using MC protocol. I want to send data from 3 of this PLCs to the 4th PLC in the same network using fixed buffer communication. Can anyone provide a sample program for the same. Send and Receive side. I am using GX Works 2 for programming. Your help is very much appreciated.

Hello! Im trying to set up Alarms on my project using GT Desisgner 3. My GOT is a GS Series, and my PLC is a FX5U. I usually just do a multi state lamp with descriptions for what's happening on the machine, but this system is much more complicated, so id like to do an alarm screen. I found a few sample projects, as well as tried both the Simple and User alarm tools on my own. However once everything is set up, when an alarm is triggered, the comment for that alarm is missing... The alarm time of occurrence, as well as turning green when its resolved all works on the screen, but i cant figure out why my comment doesn't show up. When in my project, all the "previews" of my comments show up great and are all there, just not on the screen itself... Any help would be greatly appreciated! Thanks!

Hello All, Semi-noob here with Mitsubishi PLCs. I'm starting a project in which we are upgrading an existing A Series PLC with the Q. Is there a datasheet somewhere that lists compatible software within Mitsubishi's lineup? I had no luck in searching their site. Also, (in the same project) the existing network uses DeviceNet. I have the Q series compatible card for that - but within what software does one configure the network? Thank you.

Hi Everyone, I have NT31C-ST142-V2 and it has a prompt of "System Program not exist or incorrect." I am trying to transfer via NT Series System Installer but I am getting a time-out error. I have Xm2S-09 serial cable with ATEN serial-to-USB cable.I know it is not broken since I can still Upload/download on a CJ2 PLC. I just want to know what other things I can do upload a systemprogram. I have seen a comment on this site that he remove the battery then tried to upload again. NT is almost 15 years old. I have a back-up program. I can't seem to upload by this time for pictures of theH MI and the screenshots of software .

The CC-Link system on a machine has been intermittently dropping out. Normally the Link Scan Time runs at a solid 87ms. When the system "drops out", the link scan time will increase. Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle. There are 33 stations on the network. The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.) We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane. Is it possible for one station or one of the cables to create a network wide problem? Any ideas thrown at us would be appreciated.

Hello, I seem to be having trouble reading comments from PLC in GX Developer. The PLC is an ACPU, Everytime I try to read comments using GX Developer I get the following error. "The comment was not read correctly". I found an old project from this PLC that has comments, But im unable to read any current ones. Anyone experienced this before?

Hello, I was wondering if any of you have experience translating comments. To be more specific, I have been tasked with translating all of the comments in my plant from japanese to english. We have many different series of PLCs, but they are all mitsubishi, and I will be using GXWorks 2 for 99% of them. I had the idea of writing the comments to a CSV file, Translate them there, and then just read them from CSV back into the project. I have tried numerous methods, but it seems the CSV loses format and isnt able to be read back into GXWorks. Some of these comment files have almost 10,000 comments. Do any of you have any suggestions on the best way to translate these comments over, in a more automated way than manually one-by-one. Thanks in advance for any support you can provide!

I need to communicate with a Mitsubishi PLC using Matlab. To do that, I open a serial communication with the appropiate parameters (7,e,1,9600), and write an ASCII message based on the manual I have (attached). I have tried examples as the one in the attached image. The response starts with a 6, that is, the ASCII number for ACK, so something must be working. But the rest of the response is junk (149, 149, 149...), although its length depends on the input length (if I add terminator, the response is longer, and so on). I am completely stuck. Some information that might be helpful: I am using a Serial to USB converter that I have used successfully with other PLC (which used Modbus, so everything was easier) There's a VB application (of which I don't have the code) that is able to connect to the PLC (I need to connect directly without using this intermediate app). I have decompiled it trying to get some info, but was just able to confirm the 7,e,1,9600 parameters, since the rest of the code is too mangled to analyze The attached manual was sent to me by the guy who designed the PLC and its ladder code, so I guess it is the correct one I have tried the echo mode (TT) to no avail, response is always the same I have some doubts regarding the reading of a value (see attached image). Why is there a second message from the PC? Shouldn't I just need to read the response? GX Developer tells me that the address D8120 (which is supposed to define the comm format and protocol) contains a 0, which seems weird. Any help or hint would be greatly appreciated. Thanks jy992d69901e.pdf

We have an application using a Mitsubishi L02CPU-P with a built in ethernet module. At one time the TCP/IP interface became irresponsive and a hard reset was required. The device is configured for binary communication and works fine using a GOT therminal and also operates fine when queried from a GX Works application. During debugging of a custom MELSEC application the TCP/IP interface stopped responding and could no longer be located using GX Works and the GOT terminal also lost contact. The L02CPU-P continued running the control application, but could no longer be contacted. The only way to recover was using the L02CPU-P reset button. I have heard developers being restrictive using the TCP/IP interface remotely over VPN and unstable connection due to the risk of hanging the device and not being able to recover without a personal visit to the device. Any experience from L02CPU-P devices requiring hard reset to come "online" again? Or does it enter some default state due to some internal exception handling?

Hi everybody, Is it possible to send MELSEC commands to oneself, locally, not using the phiysical ports? I would like to use some commands described in the "Communication_Protocol_Reference_Manual_(MELSEC)" to get some self-management functions in my PLC. For example, in OMRON this is possible using CMND instruction and setting the FINS address to 0.0.0 in the parameters of the instruction. Thank you very much.

Good Evening everyone, I do realise that this has possibly been done before but quite a few years ago and the links no longer seem to work or links to Mitsi pages that are in Japanese, so please excuse me. I have soem A series PLC kit that needs replacing and I have bought all new Q series stuff to replace(where possible). I have been languishing a little on this project now for a few months but need to get moving. I purchased a GOT HMI and got a good deal on the HMI and the complete Mitsubishi Software Suite the local Mitsi guru said that was all I needed to get the job done. But afetr delving into what came inthe box it seems I need a A - Q Conversion Support Tool https://www.mitsubishielectric.com/fa/products/cnt/plca/pmerit/renewal/case/support_tool.html However I cannot find the software on any of the DVD's that I have and I cannot seem to find a download. So I am stuck now. Can anyone help point me in the right directon? Any Help greatly appreceiated. Thanks in advance.

i have a 800 series vfd drive that when trying to start has the STF function and stop on at the same time, does this sound like a plc issue or a wiring issue?

I have a client who is duplicating an existing Wonderware SCADA/MELSEC Q Series with a Wonderware 2014 R2 configuration, which they want to maintain that version. The driver they use is the DASMTEthernet, which is no longer available from Wonderware. I'm looking for any lead I can find to get hold of this driver, or a good solution to resolve the communications.
